The Creative Cloud Manager will only show the version number, not the latest update. To see exactly which version is running on your computer, open Lightroom and from the main menu, select About Photoshop Lightroom CC. You will get this box which shows the latest update in the upper right hand corner.

Depending on the speed of your computer, you can also see the latest update in the Lightroom opening flash screen as you open Lightroom.
